Bruce Privacky, 16, of Ravenna was driving a Subaru Outback Legacy that hit the bus on northbound 56th Avenue at Roosevelt Street at around 2:30 p.m. Sgt. Steve Austin of the Ottawa County Sheriff's Department said Privacky and his sister, Antonia Privacky, 13 — who was riding in the front seat of the vehicle — were both killed.
Austin said the Coopersville Area Public Schools bus' flashing red lights were activated at the time of the crash, and the roadway was wet at the time. A witness said the car was traveling about 55 mph at the time and its brake lights never came on.
Police said 21 middle and high school students were on the bus, but they were not injured.
Austin said the Privacky teens' mother came upon the crash scene when she went looking for her children after they failed to arrive home on time after school. Both were Coopersville students: Bruce was in the 11th grade and Antonia was an eighth-grader.
The crash remains under investigation.
